I have a 2011 Hybrid MKZ, which of course has two battery systems: one for the Hybrid system behind the trunk and another conventional car battery under the front hood. We will be leaving the MKZ in the garage while my family is gone on vacation for 4-6 weeks. I'd like to know what prep Lincoln recommends I take with my MKZ prior to departure? (Disconnect the conventional battery? Disconnect the hybrid battery? Connect the conventional battery to a Battery Tender?) Does anyone know what Lincoln recommends?
